Slide buckle



Ja'n. 6, 1931. J. H. DOMKEE SLIDE BUCKLE Filed April 4, 1930 Patented Jan. 6, 1931 MANUFACTURING COMPANY, OF WEST I1IAFVEN, corarnner'rcnn A CORPORATION 01" CONNECTICU'T Application filed April 4,

This invention relates to slide buckles employed for adjusting the length of straps,

Webbing, ancl the like upon which the buckle is mounted, the adjustment being maintained thereby without any penetrati on'into t l1e material, and the objects of the invention are t0 provicle an entirely rigid and indestructible slicle buckle; so provide a slicle buckle that is reversible; t0 provicle a wire slide buckle 01 m integral outer ancl inner rectangular frarnes having a common plane; to rovide such a struct-ure cf whieh the outer rame provicles upper ancl lower parallel bars and 0f which tl1e inner frame provides relatively spacecl bare extending across the buckle in sp'aced relation fiothe oucer ancl inner bars, respectively; and toprovlde such an outer and inner frame structure of Whlch the metal of the respective -terrninals are united in permanent intirnate union with engaging metal 0f the frames. With these and other objects in view as may becorne apparent from he within discl0sures, the invention eonsists not only of.

t-l1e particular forrn herein pointed 01113 am]. illustrated in the drawing, but readily aclrnits of certain modifications wihin the-scope of' what hereinafter may be claimed.

The character of the improvement may be best unclerstoocl by reference to one illustrative device embodying the invention and illustrated by the accompanying drawing in which the Figure 1 is an elevation of the bnckle 0f which the reversecl elevacion woulcl be identical; ancl the Figure 2 is a top view thereof, the Figure 3 being an elevation of a modifiecl f011n of buckle.

.Referrlng more prticularly to the drawing the buckle is macle from a single piece, of wire of Which a 1nicldle portion ls bent to fo rrn an 0uter rectangular frame having the upper bar 1 and the lower bar 2 integrally connectecl by be si.ole bar 3, the opposite sicle of the enter fra1ne being formed by tl1e engaging l00pe l structure terminals 4 anal 5 provicled by bending each wire portion Within the frarne ancl back upon itself, the remaining wire portions being bent relatively spaeed and in spaced parallel relation 130 the npper ancl lower bars 1 and 2, respectively, le provicle the intermediate bars 6 ancl 7 ex- SLIDE BUCK'QE" tending relalively spa cecl across tl1e buckle,

Tl1e strueture above describecl, afid illnstratecl by the Figures 1 ancl 2, difi'ers fron1 the structure clescribed and illustrateclby the Same applicant in an application fileil December 13,-1929, Serial Nnmber 413,854c, in tl1av'; there is there disclosecl a slicle buckle Comprising a pair Of loops in a .c0lnmon plane andhaving vintermecliate bare in relatively close as'sociation, while Ehe" presenfi application 'discl'oses 1a strnketure of inner and ou'er frames arrangecl wltlii'n a com1n0n plane, the inner frame providing l1li9 relatively spaced intermediate bais. The, bars (Sand 7 1nay be of more or lessdist-an0e apart, but-lheir spaced relation t0 tl1e bars 1 an l 2, respeetively, approximately as illustrated, isbetter adapted t0 ollset a, strap (not illustrated), intencled tobe thleaclecl into the buckleinthe usualmanner th an if the bare (Sand 7 ere relatively spaced,for instance, a thirty-seconcl 0f an inch apart. The buckle i9reversible in use in-tlmt;the elevation reverse'd to that illustrtecl is iclentical therewith. The :struot-ure illustrated by the Figure 3 is sligl1tly modifieol in that, while outer and inner frames: are providecl in a common plane by bending a single length of wire, yet they are formed by doubling the wire and then bending the doubled Wre in its OWI1 plane to assu1ne rectangular forms, one within the other, and providing the relatively spaced parallel bars 1A and 6A, the relatively spaced parallel bars 2A and 7A, and the closely associatel side bars 4A and 5A of one V slde of the frames ancl the wire terminals 3A ancl 9A f0r1ning the other side. The extremities 0f the wire terminals 3A and 9A being unlted in permanent intimate union with en- JOHN II. DOMKEE, OFWES'I HAV'EN, Connncrrenf, assren'e'ip TIOLEI-IE WIRENVELTY:
